Abstract
The invention discloses a solar water heater which is composed of the light-collector, heat absorption, water pipeline, water store implement; the light-collector includes at least one strip Fresnel lens to raise the light energy density of the solar water heater, focuses sunlight on the thermal absorption unit. The Fresnel lens is a group of mutual basic parallel lens which constitutes to a plane portfolio. When the fold face of the strip and flat Fresnel lens who can bend into the bending forms the angle-fold face, trapezoid fold face, multi side fold face, it can eliminates the solar tracking system, thus the cost is Low and high efficiency.
Description
Technical field
The invention belongs to the Clean-tech field, relate to solar water heater, particularly a kind of solar water heater of focus type.
Background technology
China regulation was from January 1st, 2007, and solar water heater producer must mark on specification when selling solar water heater: in Beijing, and Xi'an, cities such as Shanghai, the water in the winter solar water heater can't reach the water temperature that can have a bath.This is based on such fact: the flat solar water heater just can obtain one case warm water (having a bath winter with 36-38 ℃ of hot water) of 28 ℃ in Shanghai winter (temperature is about 15 ℃) continuous three fine days.
Summary of the invention
Technical problem of the present invention is: described solar water heater uses the energy density that needs to improve solar source in winter.But general condenser lens is an optical glass, and is heavy and expensive.
Technical scheme of the present invention is: solar water heater is made up of light collector, heat absorber, waterpipe, water receiver.Described light collector comprises a condenser lens at least, is used for improving the energy of light source density of solar water heater, and described condenser lens is a Fresnel Lenses, with solar light focusing on heat absorber.Described Fresnel Lenses is the bar shaped Fresnel Lenses.Described bar shaped Fresnel Lenses is the triangular lens that one group of crest line is parallel to each other substantially, described triangular lens constitute a plane combination, a face of described single triangular lens is the cylinder that arcwall face promptly forms cylindrical lens, and it is identical that described bar shaped Fresnel Lenses cross section and Fresnel Fresnel lens are crossed center of circle cross section.Therefore the axis of Fresnel Fresnel lens expands to the axial plane of bar shaped Fresnel Lenses in the technical program, and correspondingly focus expands to a focal line.It is to be noted that core still keeps circular convex thin lens, so the core of bar shaped Fresnel Lenses still keeps cylindrical lens according to the design principle of Fresnel Fresnel lens.
According to one embodiment of the present of invention, can further being improved to of technical scheme of the present invention: when the axial plane and the sun of described bar shaped Fresnel Lenses moves plane, camber line place when basic vertical over the ground, the technical program need comprise a solar tracking system, to improve the capacity gauge of energy of light source, the sunshine that is morning and dusk improves the energy of light source density of solar water heater hour also can be to greatest extent the axial plane of described bar shaped Fresnel Lenses being parallel to sunshine with the ground level angle.Described tracking system comprises location, transmission system.Described tracking system comprises that navigation system is used for measuring the position of the sun and angle and sends instruction to be made transmission system work to assigned address, described transmission system have a rotational freedom axial plane of Fresnel Lenses is basically parallel to sunshine.
According to one embodiment of the present of invention, can further being improved to of technical scheme of the present invention: the solar tracking system that described solar water heater comprises, described transmission system can further have the rotational freedom of two quadratures, can be accurately the normal of the combined planar of bar shaped Fresnel Lenses triangular set of lenses be aimed at the sun substantially, to obtain maximum energy of light source density.
According to one embodiment of the present of invention, can further being improved to of technical scheme of the present invention: three faces of the triangular lens of the triangular set of lenses of described bar shaped Fresnel Lenses are common plane; I.e. one group of triangular set of lenses that corner angle are different, promptly the arcwall face of original described single triangular lens will be replaced by its string plane.Having had its effect of scattering effect thus is that focal line expands to the focusing light belt with certain width, has improved the absorption efficiency of heat absorber effectively.
According to one embodiment of the present of invention, can further being improved to of technical scheme of the present invention: describedly constitute the bar shaped Fresnel Lenses that a plane is combined to form by the triangular set of lenses, it is become curved surface along the crest line integrally bending, all crest lines all become circular arc, and become the circular arc of the center of circle on same axis basically, described axis is parallel to the normal on each plane, circular arc crest line place.The present technique improvement project when not being equipped with solar tracking system, in the morning with the sunshine at dusk with the ground level angle hour, also can with solar light focusing on heat absorber, when basic guarantee absorbs most of solar energy, reduce cost widely.
According to one embodiment of the present of invention, can further being improved to of technical scheme of the present invention: described integrally bending becomes the bar shaped Fresnel Lenses of curved surface to be replaced by the folding face combination that plate bar shaped Fresnel Lenses is converted into.To be plate bar shaped Fresnel Lenses with its vertical direction bending along crest line once become specific practice that face is rolled in angle type folding face, bending for twice in echelon, bending repeatedly becomes polygon folding face.The present technique improvement project can be used the bar shaped Fresnel Lenses of plastic board section bar cheaply, has therefore further reduced cost.
According to one embodiment of the present of invention, can further being improved to of technical scheme of the present invention: the material of described Fresnel Lenses is transparent macromolecular material.
Need to prove: present patent application has used this term of rod lens to summarize the notion of cylindrical lens and prism compound lens.The implication that present application for patent has been used basic vertical this term is constant substantially as angle physical meaning and the industrial value of technical scheme that change slightly when spending as 85, and is constant substantially as energy density, or changes minimum.
The invention has the beneficial effects as follows:
Solar water heater is by condenser lens, improves the energy of light source density of solar water heater, and described condenser lens is the bar shaped Fresnel Lenses, with solar light focusing on heat absorber.The present invention at first is that one group of mutually substantially parallel triangular cylindrical lens constitutes a plane combination with described bar shaped Fresnel Lenses, and it is identical that described bar shaped Fresnel Lenses cross section and Fresnel Fresnel lens are crossed center of circle cross section.Therefore the axis of Fresnel Fresnel lens expands to the axial plane of bar shaped Fresnel Lenses in the technical program, and focus expands to a focal line.Proposed to cross, owe focussing plane and curved surface improvement project, the triangular cylindrical lens is improved to the triangular planar lens, overcome conventional lenses and focused on focal method for designing, the light absorption face that all strengthened has improved efficient and life-span.Triangular cylindrical lens plane is become curved surface with buckling and is bent into the combination of folding face, make the present technique improvement project not be equipped with solar tracking system, in the morning with the sunshine at dusk and ground level angle hour, also can with solar light focusing on heat absorber, when absorbing most of solar energy, basic guarantee reduce cost widely.Obtain the advantage of the ratio of performance to price, greatly reduced maintenance and regular maintenance cost in addition.In sum, the present invention has reached Patent Law and has required to have outstanding substantive distinguishing features and obvious improvement.
